The stochastic discount factor (SDF) method provides a unified general framework for econometric analysis of asset pricing models.

In this paper we develop alternative ways to compare asset pricing models when it is understood that their implied stochastic discount factors do not price all portfolios correctly. Unlike comparisons based on x2 statistics associated with null hypothesis that models are correct, our measures of...
